you can get any kit leading up to stage 2. there is a stage 1, 1 to 2 and 2. stage 2 comes with everything in stage 1 and then some. for more information please use the search option cus most of the questions you will have are likely already answered.

Has anyone done the ECU reflash themselves? If so, is the VCI code the TechLine Rep gives you that is needed to do the correct reflash going to be the same on most or all cars?
The reason why I'm asking is I work at a GM dealership in the parts dept and have full access to the Tech 2 whenever I need it. It would save a lot of us readers time if some one could post the VCI code.
I would even say PLEASE!!

the code is unique and uses the number provided with the kit and your vin number. You will have to pay to get it flashed just like everyone else. Wanna play gotta pay

Thats the good thing about here. Once I get the number that is on the instruction sheet, I can call and do the flash myself costing me nothing.
Thanks for the info on the VCI code thing. I like learning something new.

Are you guys all from the us? i am from canada and i bought the stage 2 kit and my dealership wont even install it.. and they told me there was no warrenty if i got somone to put it in? n e one heard n e thing like this b4?

1) When GM announced the kits, the advertised increases of 31 HP (236 HP net) for stage I and 36 HP (241 HP net) for stage II (see pics below). Why does everyone keep saying you get 245 HP from stage II??? Did GM change the specs on them or something, or is everyone just misinformed about what they actually give you.

2) Does anyone have a before (stock) and after (stage II only) dyno that shows the power gains?

i believe some of the info got updated cus if you look at the description on a website that sells the kit it will mention the 245hp. I was gonna do before and after then I saw the price of going to a dyno here in phx and I decided the money is better spent on mods

Humh...

Crate Engine Depot has these posted which coincide with the GM numbers:

Just finished reading 7 pages of this stuff. If I was to just get the GM Stage 1 only, can I run a 2.7 pulley with the same injectors or just stick to 2.8 pulley? I know that with the 2.8 you dont have to change anything. I dont see why people are getting the GM stage 2 when its just a belt and a 3.0 pulley for hundreds of dollars when a pulley costs like 50-60 bucks and the tensioner is about 80-100.

It also comes with new injectors and the computer reflash. Plus the warranty.

the ecotec is a proven platform. this engine has user build books to help enthusiates reach rediculous amounts of power. In stock form the ss/sc has parts that easily allow for 300hp and after that only a few mods would be needed to upgrad further. The only issue is getting their which is half the fun. With any addition of mechanical power there has to be an assumed loss of life on the engine but the ecotec has that covered as well as the engine should be good for an easy 200k+ miles stock.

edit: the ecotec loves boost and 18psi would be no issue for it to handle. I am running roughly 16~psi at this time and the car feels like it absolutely gets loves it. Reliability is one of the reasons the kit took so long to release from GM cus in order for the kit to be released they had to pass such tests which would include reliability as one of the pre requisits

Thank you VERY much OniMirage that makes me feel much better about my purchase.

I would love to push 300HP and I think I would stick around that range since I don't race.

I'll do some more searching about how to get up to 300HP. there is a lot of info here but WOW it is scattered all over the place.

my biggest fear is moving up past the GM stage kit then having an engine failure and scewing my 6 year warranty. I have been looking inot the Magnuson Moss act.. but I am not entirely comfortable yet. I suppose most of this stuff is bolt on/ bolt off so easy to revert back to stock. just not sure about the ECM programming and stuff. WOW

I do appreciate your help guys

If you are worried, go GM stage II. That is what I am doing. I'm not doing stage I with a non-GM pulley either. I'd rather have it all covered in warranty.

As far as reliabiltiy goes, the ECOTEC line is incredibly reliable. They are capable of making tons of power. I know lots of people who had the 2.2L when it came out and had rung the sh%t out of them, and they still run like new years latter. The engines are bulletproff. You'd probably be OK with some of the Intense kits, but I don't think it is worth the risk when there are kits available to carry a full warranty. Just my opinion though. If you want big power, your better off not going with the GM kits.

I'll go with GM stage 2 to start with. once I am comfortable with that and used to reading the scan gauge and getting a better feel of the over system and it;s effects on various sub-systems I think I will slowly move up the ladder.

the best thing I have heard today is that the ECOTEC is bullet proof. that really gives me confidence.

I am running AEM CAI and an ingalls engine brace now. WOW the brace made a huge difference.

as long as you dont go smaller than a 2.8 stage1/2 tune will be ok
also not advised to run a CAI and 2.8 pully.

Why not? What do you mean by not advised to run a CAI and 2.8 pully? Do you mean, Don't mix the two AT ALL? or don't put on a CAI and then add a 2.8". I've got the Fujita, Stage 2 and am getting ready to put on a 2.8". Wow, this is the first I have heard this... you got me worried... and probably needlessly.
